According to a New York Times article, new studies indicate that kids who spend time in daycare before they were 2 have a lower chance of developing childhood leukemia. The theory is that by being exposed to different germs the immune system gets stronger as it fights them and doesn't ramp up to a point where cells start quickly dividing, potentially causing leukemia or other cancers.
Sanjay Gupta, CNN's health expert, said in his report that while this is the first study to show that daycare might be good for cancer prevention, there have been others that indicated it might help prevent things like diabetes and asthma. It seems it's all about the germs -- getting exposed at an early age to other kids who have tons of them and building up an immune system that can fight them is a very good thing.
If your kids are in daycare -- or were when they were younger -- is this something that makes you feel better about the choice you made to put them there?
